Ecoglo® F4170 Non-Slip Flat Stair Nosing with Black Insert – 2.7" Wide

Model F4170 • F4-N20 Series Ecoglo® F4170 Aluminum Flat Stair Nosing – Black Non-Slip Stair Protection Improve traction, define stair edges and protect high-traffic steps with a durable 2.7-inch-wide aluminum non-slip stair nosing. The Ecoglo® F4170 Non-Slip Flat Stair Nosing combines a durable clear-anodized 6063-T5 aluminum profile with a hard-wearing black silicon-carbide non-slip insert. The right-angled profile fits over the leading edge of an existing stair to provide dependable traction, visible step-edge definition and durable protection in high-traffic applications. Designed for commercial, institutional, industrial and public stairways, the F4170 can be installed on concrete, timber, tile, steel, checker plate and suitable thin carpeted stairs. It provides a practical solution for upgrading worn or slippery stair edges without replacing the complete stair assembly. Product Configuration Model F4170 is part of the Ecoglo® F4-N20 non-photoluminescent flat stair-nosing series. It features a clear-anodized aluminum profile with a black silicon-carbide non-slip insert. The black insert provides traction and visible step-edge contrast but does not glow in darkness. For the black-anodized profile with a black insert, select model F4270. ✔ Model F4170 ✔ 2.7-Inch-Wide Profile ✔ Black Non-Slip Insert ✔ Indoor & Outdoor Use Hard-Wearing Slip Resistance The silicon-carbide non-slip material is integrally bonded to the aluminum substrate to provide durable traction for heavily travelled stairways. Black Step-Edge Contrast The black non-slip insert creates a clearly defined stair edge where it contrasts with the surrounding tread surface, helping improve step-edge recognition. Stair-Edge Protection The right-angled aluminum profile covers the leading edge and vertical face of the stair to help protect vulnerable edges from repeated foot traffic and wear. Indoor & Outdoor Durability The F4-N20 Series is tested for UV exposure, salt-spray resistance, freeze-thaw resistance, abrasion and washability for demanding stair applications.
